Subject: [PATCH 01/17] MIPS: BCM47XX: move the nvram header file into common
|
|
space
|
|
|
|
Moving mach-bcm47xx/bcm47xx_nvram.h to include/linux/bcm47xx_nvram.h
|
|
makes it possible to reuse this header on the ARM based bcm47xx/bcm53xx
|
|
SoCs (e.g. BCM5301X devices). Broadcom uses ARM CPUs in their new SoC
|
|
form the bcm47xx and bcm53xx line, but many other things like nvram
|
|
stayed the same.
|
|
|
|
This is a preparation for adding a new nvram driver, which can be used
|
|
by the ARM SoC and the MIPS SoC code. The device drivers accessing
|
|
nvram do not have to care about ARM or MIPS SoC version.
|
|
|
